Consistent with E.O. 13132, Federalism, the EPA, Department of Army, and the Army Corps of Engineers consulted with state and local government officials, or their representative national organizations, while developing a revised definition of "waters of the United States." The agencies consulted due to strong interest on the part of state and local governments on this issue over the years and potential effects associated with a change in the definition of “waters of the United States”.

In addition to an initial Federalism consultation briefing held April 19, 2017, the agencies convened several additional meetings with intergovernmental associations and their members in states and communities to solicit input on the proposed revised definition of "waters of the United States" (WOTUS) consistent with the February Executive Order, the Clean Water Act, and U.S. Supreme Court opinions.
